Many of us dreaming of living on other satellite , but are two things we ’ll require before it can actually fall out : money and raw materials . Now some troupe say they have a solution to this problem . They ’ll mine asteroid for valuable metal ores , and for basic resourcefulness like water that we ’ll need once we ’re far from Earth .

Lucky for us , the cosmos is packed with the rude materials we demand and crave . disperse across our galaxy are trillions upon trillions of space stone , filled with the water , wanted metals , and other raw materials we ’ll need to fire our cosmic diaspora .
Mining asteroids is not just a dream — several enterprising companionship are already father the jump on it . Still , the technical barrier are huge , and we ’re just beginning to come to grips with the social and political implications of a space - base civilisation . Here ’s what we already know — and need to know — about the industry that could make it come about .
A Solar System of Riches
Over four billion age ago , the planets and moons of our solar arrangement began to coalesce from primordial debris . So , too , did the asteroids . While we ’ve do it about space rocks for overtwo century , the huge absolute majority of discoveries have been made in the last two X , thanks to liberal and unspoiled scope .
To date , we ’ve name some 10,000near - worldly concern asteroids , ranging in size of it from several measure to hundreds of kilometers across . If that number sounds telling , rest assured it ’s not : By some estimates , there are upwards of a150 millionasteroids in the privileged solar system alone .
Astronomers keep to turn up more space rocks on the daily , but we ’ve already found tidy sum to be excited about . Many of the asteroids out there are loaded with water , a resource that may , in space , be more valued than amber . As Chris Lewicki , chairperson of the asteroid mining companyPlanetary Resourcesexplained when I utter with him over the phone , some of this water could be commute to skyrocket fuel by splitting off the hydrogen . Wet asteroids , then , may serve as cosmic petrol place ; irrigate holes for thirsty spacecraft and man likewise .
“ When you launch a satellite up to orbit , two thirds of the weight is fuel , ” Lewicki said . “ If we could only refuel things without sending them back to Earth , that would open up up a wandering main road . ”
tempting as that sounds , water is n’t even the most valuable commodity locked up inside asteroids . That ’d be platinum , and its babe metal , which , renowned for their undischarged catalytic properties , are used in everything from computer knockout drives to fuel cells to biomedical equipment . On Earth , these metals are extraordinarily uncommon : All of the atomic number 78 humans have ever managed to dredge from the ground , for illustration , could meet inside a small Manhattan flat . A 500 - metre asteroid might contain more .
There ’s a reasonableness the individual sphere is now clamoring to get into space . The first successful asteroid miner may become richest human beings alive .
But before we can start trucking platinum en masse from the wizard , space miners have their study abridge out designing , test and deploy the myriad technologies needed to do so . The two company chair the charge , Planetary Resources andDeep Space Industries , have hoard a slew of scientists , engineer , entrepreneurs and investor to make it happen .
Asteroid Prospecting
The first task on any would - be asteroid miner ’s list is to start pinpointing some severely lucrative rock . While we ’ve got passel of near Earths to pick out from , a trip to any one of these neighboring bodies is still a major investment , so before we send out the drills , we ’d like to get as much intel as we can from afar . This , it flex out , is no piffling trouble . Asteroids are small , grim , and difficult to make out within Earth ’s becloud atmosphere . In fact , the best way to get a good look at an asteroid is to put a cathode-ray oscilloscope into place .
That ’s precisely what Planetary Resources is planning to do . ItsArkyd-100 , a crowdfunded scope that weighs less than 25 pounds , will sit down in low Earth ambit , peering into nearby space to canvass targeted asteroid . The next - gen rendering is theArkyd-300,fondly describedby company leaders as humanity ’s first Imperial Probe Droid . The 300 - serial Arkyds , equipped with propulsion system , will travel in swarms to nearby asteroids . Once they ’ve pass on a aim , the bots will examine the rock candy in detail , measuring its size , configuration , density and primary report , and beam the specs back to Earth using optical maser - establish optical communications .
The company has plans to launch two beta droids this year . If all croak well , the Arkyd-100 will launch in 2016 , and the first of the Arkyd-300s will blast off in 2018 .

Deep Space Industries is also planning to start small-scale , using price - effective prospect crafts to direct the initial survey body of work . In 2017 , the company hope to plunge its very firstFireFlies , laptop - sized spacecraft destine for one - elbow room asteroid recon charge . After targets are corroborate , the quality rock’n’roll will be inflict a 2nd time with “ DragonFlies ” , which’ll bring samples back to Earth for detailed analysis . finally , “ Harvestors ” may be sent out to quite literally pull the most hopeful all-day sucker back to us .

Juicing a Space Rock
For mining water , we ’ll probably go after carbonaceous chrondrites , or deoxycytidine monophosphate - type asteroids — wet , crumbly rock with an elemental composition standardised to that of the sun . AsPopular Mechanics describes , Planetary Resources envisions using its Arkyd swarms to slurp up rough regolith and funnel the stuff into a mainframe . The weewee can then be steam off and recollected in a separate armored combat vehicle .
A subset of the rocks we pinch for weewee — the so - called L4 chrondrites — may also be robust in atomic number 78 - group metals . How we extract these metals is probable to depend on a legion of factor , including their concentration and the sort of intercellular substance they ’re embedded in . “ quad rocks are all different , ” Rick Tumlinson , Chair of Deep Space Industries , told me in an electronic mail . “ There is no one - size - fits - all solvent to educe what we involve from them . ”
Even so , both companies have floated some intriguing hypothesis . wandering Resources cofounder Eric Andersonhas describedhow we can use the sun ’s energy to essentially mellow down asteroids and concentrate the hotness - tolerant platinum - radical metal . Anderson goes on to explain how elephantine bollock of the platinum might be safely returned to Earth by drop them into an uninhabited desert somewhere .

Several weeks ago , DSI herald that it ’s investigating the feasibleness ofinjecting bioengineered , metallic element - munching microbesinto space rocks . The idea here is that these excavation bugs will , over the form of old age , masticate up an asteroid from the inner out and decoct the metal for us .
“ sealed living creatures , called extremophiles , are able to survive and thrive in environments that would blow your mind , including nuclear reactor , ” Tulminson said . “ Eventually , we believe that genic variants of these and similar creatures might be used in space mining processes . ”
It ’s an awing idea , but , research worker have been quick to point out , one that ’s still very , very preliminary . ( There ’s the small challenge of genetically direct a microbe that ’s able-bodied to sustain a hearty metabolism in the harsh vacuity of space for years on death ) . At this point , it seems safe to say that any and all options — blasting , melting , feeding , vanish , magnetically separating — are on the mesa .
Who Owns the Asteroids?
As we move ever closer to a quad - mining time to come , some thorny legal head have begun to nurture their heads . To card , under current law , it ’s unclear who , if anyone , can legally own an asteroid — a fact which is making early investors wrestle in their butt .
“ Anybody who wants to go to an asteroid now and extract a resourcefulness is face a turgid legal open question , ” space attorney Joanne Gabrynowicztold NPRin an interview earlier this month .
Space is aglobal green , intend that all nations have the right hand to use it and search it . But when it come to staking out resources in quad , we ’ve yet to reach any sort of concord . Since the United States has duty to regulate its secret blank space enterprise under external police , the largely US - free-base asteroid minelaying industry has been pushing Congress to happen statute law clarifying the matter .
This past September , the House Science , Space and Technology Committee take a sense of hearing on the Asteroid Act , afive - Thomas Nelson Page billthat would recognize ownership by company of the imagination they ’ve extracted from asteroid and , foreclose company from interfering with the operation of challenger . AsSlate reportedthis past declivity , the handbill was run across with support from the commercial-grade space residential area , but unfavorable judgment from legal expert . Gabrynowicz , for one , feels that the vizor bomb to handle all-embracing - ranging outlet , include whether granting mining rights to a US ship’s company is in reality sound under international law . You have sex , details .
For now , at least , it ’d seem the asteroid are first number , first serve . We ’re becoming the maven of our very own space western .
Post-Earth Economies

Space may be a anarchic frontier right now , but this just the source . It ’s not toilsome to think asteroid mining taking off within the century , and with it , multiplex new opportunities for geographic expedition and development opening up . In the future , Deep Space Industries envisions a organisation of infinite - based manufacturing , wherein asteroid metals arefed flat into 3D printersto build new mining gear , political program , and even outer space home ground .
If , as today ’s quad trailblazer hope , we can start to build and fuel structures off - mankind using asteroid - educe materials , that abbreviate out a very expensive middleman — Earth . At which compass point , manned interstellar missions and outer space settlements might be within reach . One can think asteroid terminal disperse across the stars , resupplying our 3D - printed spaceships with atomic number 1 fuel , water , and replacement parts .
“ If the door to long - terminal figure space locomotion will ever be opened , it ’ll be open up by using the resourcefulness of blank space , ” Lewicki said . “ From an exploration viewpoint , this is the next expectant get-up-and-go . ”
As dangerous as it might be , it ’s backbreaking to refuse the call of the frontier . If somebody offered me a pick , a spacesuit , and a slate up , I ’m not sure I could refuse .
